Abstract (en)
An instant photographic film unit includes a mask sheet (24) having an image frame (22) and two sheets (30), (36), one of which has a photosensitive layer, laminated and bonded together, and a developing liquid container (40) disposed in a predetermined position for supplying a developing liquid between the two sheets (30), (36) to produce an image. The mask sheet (24) and the two sheets (30), (36) are bonded together in a predetermined laminated state, with at least one of the mask sheet (24) and the two sheets (30), (36) being in the form of a continuous web. The continuous web is cut off into self-developed instant photographic film units (20) of a predetermined length. A predetermined number of instant photographic film units (20) are automatically stacked and placed in a film pack (82). <IMAGE>
